We have just had a roof light 1000m x 1000m installed to our fibre glass roof. Cost £2000 to remove smaller window, and install bigger window, plus plastering...we paid for window separately. The plastering inside is wonderful, but we are not happy with the finish of the fibre glass repair. Please see photo showing rough texture of glue that cured to fast? It looks way to messy. Workers tell us that's the way it goes it you dont have full roof done....I'm not convinced...
Not so great they paint it different colour either. Dark grey , when my roof is mid grey.
Opinions please ...
